Mary-Kate Olsen splits with her beau

[HMG] – For those of you to whom the merest glimpse of Mary-Kate Olsen is a seismic event, we have some good news — She and her boyfriend have split up for good.

Now 23, the actress, producer, fashion maven and upcoming media mogul has called it quits in her short-lived connection with boyfriend, Nate Lowman, according to Us.

And the split has since been confirmed by her reps.

Introduced by mutual friends, the pair began dating in 2008. Last year, rumors emerged that they were getting engaged — but those were shot down in flames by the same reps who now say the whole deal is over.

In October we also reported that Nate was being pressured by both Mary-Kate and her sister to sign a pre-nup before any marriage. Could the lack of that form be the reason he’s gone?

It’s not known how Nate’s taking the news, but Mary Kate’s currently keeping busy by scouring the shows at London’s Fashion Week. If she finds inspiration it may even help the sagging sales of her clothing at Wal Mart.

But don’t feel sad for her, guys — At 17, Mary Kate and her sister had a net worth of $150-million – each. Experts then predicted their production company, ‘Dualstar,’ plus the clothes, DVD’s, TV re-runs and other cash-cows would make them both billionaires by age 21.

Mary Kate turned 23 last June 13. And for someone so clearly in love with her money, who needs a guy?
